i also agree with mrstickball. the main thing is that MS has a long term plan and games like that tend to establish the xbox(s) in japanese minds. The first one was "yo i'm here, look at me". the second is "see, i can do games as well as the other 2" , so that the 3rd one can be "come in, you know me, i'm like family".
If MS sells 1 million x360, i think they have a good chance to be more than a sparring partner in the future generation.
